I had some troubles (and still having some) with the gc also.
I guess the registers aren't much of a problem, cause they will get
overriden sooner than later.
In almost all cases the 'unused' objects are getting collected if you
leave method scope, if you stay inside a local scope they often stay
alive.
Realy nasty problems seem to arrise with threads. There are examples
(in this ML) where a prog with only 2 Threads alive at every given time
keeps allocating memory until it crashes.
